Thanks for your confirmation.
For our issue of not able to send messages after upgrading to protobuf

java.lang.UnsupportedOperationException: This is supposed to be overridden
Some other sources on the net saying messages compiled with a particular
version of protobuf would not work when run with a different version of
Is there a solution to this issue, provided that I won't be able to change
the API that depends on protobuf 2.4.1?
